ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 634,248, dated October 3, 1899.

Application filed February 1'7, 1899. Serial No. 705,854. (No model.)

To ctZZ whom, it may concern:

Be it known that we, CHARLES SONNEBORN and PAUL R. KAMMERER, residents of Braddock, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Advertising Apparatu's; and we do hereby declare the following to be a full clear, and exact description thereof.

Our invention relates to advertising apparatus.

The object of our invention is to provide a simple and convenient means of changing the advertising-cards in that class of advertising apparatus in which the advertising-cards are rolled up on a roll and dropped therefrom in succession to be exposed to view through a suitable opening-in the frame containing the roll. To these ends our invention comprises the novel features hereinafter set forth and claimed.

To enable others skilled in the art to make and use our invention, we will describe the same more fully, referring to the accompanying drawings, in which- Figure 1 is a longitudinal section of a suitable roll embodying our invention. Fig. 2 is a side view of a portion of a-suitalole frame for carrying the roll and advertisements with side plate removed to show the construction of one end of the roll.

Like letters of reference indicate like parts in each View.

In the drawings, the letter a designates a frame or casing of any suitable construction, which is provided with the openings 1) b in the front face thereof. The upper portion Ct of the frame with the opening Z) therein is curved to conform to the roll a, which carries the advertising sheets or cards m. The roll 0 has the central shaft 0, which connects the end plates 0 0 These end plates have the journals c, which are mounted on suitable bearings a in the frame a. The end plate 0 has the pulley e, which is connected up by a belt to a suitable motor. The end plates c c of the roll 0 are adapted to support the rods i, said rods at one of their ends fitting in seats t" in the end plate 0 the opposite ends of said rods fitting in openings 45 in the end plate 0 disk 70, which is formed of suitable spring thereto.

Secured to the end plate 0 is the metal slitted radially. This provides a series of radial spring-arms 70 in line with the openings 1' of the end plate 0 one for each of said openings. By this construction the rods i may be readily inserted and withdrawn from the roll, as by inserting the rods into the openings 1' the arms 7): will yield and permit of the insertion of the opposite ends in the seats 1' of the end plate 0 as clearly shown in Fig. 1. The rods t maybe composed of wire of any suitable gage, great rigidity not being an essential feature of said rods.

Connected to each rod 71 is an advertisingsheet m, which maybe formed of paper, cloth, or other material which will roll up on the roll 0. Both sides of each sheet bears. an advertisement printed or otherwise applied The free ends of the sheets m are attached to rods m, which prevent the curling up of the sheets when in their suspended positions and at the same time furnish the weight required to drop the sheets after the roll has passed beyond a certain point, all of which will be more fully hereinafter set forth. At about the mid-portion of the frame a, above the frame 0, is the spring-arm n, attached to said frame at 11. At the outer end of said arm is the idle roller 01 The springarm a acts to hold the roller 01 normally in contact with the sheets on rolled on the roll 0. The advertising-sheets to be used are socured to the roll in the manner hereinbefore set forth, said sheets when rolled up on the roll overlapping each other in the manner illustrated. \Vhen power is applied through the motor to rotate the roll 0, there will always be two advertisements exposed to View through the openings 1) b, that seen through the upper opening I) being rolled on the roll 0 and that seen through lower opening I) being suspended from said roll, as clearly shown in Fig. 2. As the roll continues to rotate in the direction indicated by the arrow, Fig. 2, the sheet exposed at the upper opening 12 will move until the rod m at its free end passes beyond the roller 01. the arm n yielding sufficiently to release said rod. The arm a prevents the sheet from falling before the proper time, and only one sheet can fall at a time. Immediately the rod m is released said rod will drop of its own weight, falling down through the space 0 between the roll 0 and front of the frame. As soon as the rod m passes beyond the space 0' it will swing the sheet down to a suspended position in front of the opening Z). By this falling of the sheet the said sheet has been reversed and the advertisement on that side is exposed to view, while the sheet on the roll just beneath that one which has just fallen is exposed at the upper opening Z). The roll may be arranged to rotate at any desired rate of speed, preferably at a slow rate, in order that the advertisements will remain exposed for a sufli oient length of time to permit of the viewing and reading of same. After the apparatus has been once set in motion no further attention need be given to it, as the advertisements will follow each other in regular succession. The sheets may be quickly removed from the roll and new ones substituted when desired, so that the advertisements may be transferred from one machine to another and a variety maintained.

\Vhat we claim as our invention, and desire to secure by Letters Patent, is

1. In advertising apparatus, a suitable frame, a rotatable roll mounted therein, one of the ends of said roll having seats therein, the opposite end of said roll having openings therein, a spring-metal disk secured to the last-mentioned end of said roll, said disk having radial slits to form spring-arms in line with said openings, and rods adapted to enter said seats and openings in said ends, substantially as set forth.

2. In advertising apparatus, a suitable frame, a rotatable roll mounted therein, one of the ends of said roll having seats therein, the opposite end of said roll having openings therein, a spring on said roll in line with each of said openings, and rods adapted to enter said seats and openings, substantially as set forth.

In testimony whereof we, the said CHARLES SONNEBORN and PAUL R. KAMMERER, have hereunto set our hands.
